Geometric Optimization of Micromixers

M. Jain[1], A. Rao[1], K. Nandakumar[1]
[1]Cain Department of Chemical Engineering, Louisiana State University, Baton Rouge, LA, USA

The performance of a homogeneous T-mixer can be enhanced significantly by the stimulation of secondary/ transverse flows in the microchannel. Various mixing mechanisms are reported for enhancing micromixing performance such as grooves at the channel bottom, heterogeneous charge patterns ... Mehr lesen

Computationally Assisted Design and Experimental Validation of a Novel ‘Flow-Focussed’ Microfluidics Chip for Generating Monodisperse Microbubbles

M. Conneely[1], V. Hegde[2], H. Rolfsnes[1], A. Mason[2], D. McLean[1], C. Main[1], F.J.D. Smith[2], W.H.I. McLean[2], P.A. Campbell[1]

[2]School of Mechanical Engineering, Gyeongsang National University, Jinju, Gyeongsangnam-do, Korea

Voids in composite materials can lead to degraded structural performance. The following is a study of voids or bubbles in uncured viscous polymer resin during composites processing. The goal is to determine if voids can successfully migrate towards vacuum pathways, coalesce with the ... Mehr lesen

Computational Analysis of Evaporation in Tailored Microchannel Evaporators

S. Arslan[1], J. Brown[1]
[1]Lawrence Technological University, Southfield, MI, USA

The rapid increase in power densities of integrated circuits has induced a significant interest in new reliable and high heat flux cooling technologies. The implication of such growth is the increased need for more efficient and more compact cooling mechanisms. Promising research has ... Mehr lesen

The Effects of the Electrical Double Layer on Giant Ionic Currents through Single Walled Carbon Nanotubes

G. Zhang[1][,][2][,][3], S.L. Bearden [1]
[1]Department of Bioengineering, Clemson University, Clemson, SC, USA
[2]Department of Electrical and Computer Engineering, Clemson University, Clemson, SC, USA
[3]Institute for Biological Interfaces of Engineering, Clemson University, Clemson, SC, USA

Electrofluidic transport through a single walled carbon nanotube (SWCNT) is enhanced by electroosmosis. Electroosmosis is made possible in these devices by the combination of a large slip length within SWCNTs and the interfacial potential at the solution/nanotube interface. A ... Mehr lesen

Numerical Study of Droplet Formation inside a Microfluidic Flow-Focusing Device

Y. Li[1], M. Jain[1], K. Nandakumar[1]
[1]Cain Department of Chemical Engineering, Louisiana State University, Baton Rouge, LA, USA

The micro-nanometer sized droplets have tremendous applications in bio-diagnostics, polymerization processes etc. In this work, we numerically investigate the droplet formation process of silicone oil in aqueous solution in a MFF device. A conservative level-set method is adopted to ... Mehr lesen

Piezoelectric Buzzer Optimization for Micropumps

[1]Universidade Federal de Campina Grande, Campina Grande, PB, Brazil
[2]Instituto Federal de Alagoas, Maceio, AL, Brazil

Piezoelectric buzzers are low cost devices which can be used successfully as actuators in diaphragm-based micro-pumps. The buzzers are piezoelectric wafers (lead-zirconate-titanate-PZT) that are glued on a brass membrane and they are available within different sizes and thicknesses. For ... Mehr lesen
